Is it a good idea to try taking down the pot on the flop? I dont know his barreling tendencies, so it will be hard for me to ch/call on many turn/rivercards, and after my chRaise he could even fold stronger hands, like 99/TT, if he is a weaker type, even Jx or overpairs.

Wouldn't say that you are always making TT/99 in those to fold but clearly it could be possible. So yeah, it's still possible as long we are against UTG range and still some part of his range hasn't hit the flop.
